Bangkok, July 16 (Reporter Chen Qianci Gao Bo) Six foreigners were found dead in the hotel room in a well-known hotel in Bangkok, the capital of Thailand, on the 16th. Police said the exact cause of death remains to be investigated.

Thai Prime Minister Saita said at a press conference that night that the six dead, including four Vietnamese and two Vietnam-Americans, died about 24 hours, and there were no signs of conflict or fighting at the scene. He requested that an investigation be launched into the case as soon as possible.

Bangkok City Police Commissioner Tidi said at a press conference that night that the six victims were three men and three women. There were traces of drinking tea or coffee in the room, and the residue in the cup had been sent for inspection. The police initially concluded that suicide was ruled out and the exact cause of death was pending further investigation.

Previously, several Thai media first reported that a shooting incident occurred at the hotel, and later corrected it to the death of 6 people or cyanide poisoning. (Participating reporter: Lin Hao)

Washington, March 14 (Reporters Xu Yuan and Xiong Maoling) Data released by the U.S. Department of Labor on the 14th showed that the U.S. producer price index (PPI) rose 06% month-on-month in February, an increase of 03 percentage points from January, highlighting that the U.S. inflation situation remains severe.

Data showed that the U.S. PPI increased by 16% year-on-year in February, the largest increase since September 2023. Excluding food, energy and trade services prices, core PPI increased by 04% month-on-month and 28% year-on-year.

In the same month, commodity prices increased by 12% month-on-month, the largest increase since August 2023. Among them, natural gas prices rose 68%, and grocery prices rose 1%. At the same time, service prices increased by 03% month-on-month.

PPI tracks changes in production costs and is a key measure of inflation. Analysts believe that PPI accelerated again in February, indicating that inflationary pressures in the United States continue and the Federal Reserve may need to maintain high interest rates for a longer period of time.

A tracking data from the Chicago Mercantile Exchange showed that after the PPI data was released, the market basically believed that the Federal Reserve would maintain the target range of the federal funds rate between 525% and 55% at the monetary policy meeting held from March 19 to 20.

　　Life is a fleeting moment in the river of time, mankind do everything possible to seek forever and everlasting, but did not think, in fact, as long as the pace of their own slow down mentality flat, live in the present, then life will naturally become long and distant .It is strictly required by such a standard, pu-erh tea Only with today’s development scale, can we have the proud momentum to crush our competitors.

　　When I did not write a magazine before, I did not know that the time had come in advance. A draft of March or even April has been prepared in January. In the draft of the forum while watching the side gripped, his year has not yet ended, did not make a point, there people work has been a year, almost equal to the end. Years here, was actually can not wait to catch up with the speed of flight, how to make people panic?

　　The length of time is defined by man himself. 365 days a year, divided into four seasons, twelve months. Here, people always catch up with me like the game, to see who can one day into a day. Our ancestors know, if the decade into a year, we will so impatient it?

　　Days not used, can only be used to recover. Self has no intention to enter this door, it fell into such a turbulent swirl. Calendars and clocks on the numbers can only represent the past, because today to do, is already the future. Obviously is the spring, but the men have been doing non-stop fall thing.

　　There is nothing worthy of gratification, no reason for youth just a short length of a bit like others. What is the use of walking in front, time falls behind, urging the old soul and face it in vain.

　　The fast pace of modern people, nothing more than to speed up the clock of life, their own pressure and persecution of a way, only to more fully squeeze the juice of life to obtain value and fame. But I see it is faster and more leave no room for the consumption and flight. How, a ton of gold can be exchanged for even a second time?

　　Americans always run in front of the world, even spend today are tomorrow, the result? The financial crisis has finally shattered this myth of early consumption, punish all activities contrary to the laws of nature.

　　Beijing, then, a little leisurely. People live I, a spring vegetation, how short and beautiful time. If you can walk, why should anxious to run, miss the scenery all the way? Note that the front is not another spring, but has been waiting for you to close the end of life.

　　Tomorrow’s thing is done today, and next year’s event is finished this year. So ahead of the outstanding achievements and efforts, but is a result of the advance of life.

　　What is a rivers and lakes years reminder, juvenile children rivers and lakes old? This is the helplessness of life rather than enjoyment.

모모1. Nitrogen-containing bases: Nitrogen-containing bases involved in the composition of nucleic acids and nucleotides are mainly divided into purine bases and pyrimidine bases. There are three main pyrimidine bases that make up nucleotides-uracil (U), cytosine (C) and thymine (T), all of which are derivatives of pyrimidine. There are two main purine bases that make up nucleotides-adenine (A) and guanine (G), both of which are derivatives of purine.

모모

모모2. Pentose: There are two main types of pentose in nucleotides, namely 붹-D- ribose and 붹-D-2- deoxyribose, and the resulting nucleotides are also divided into ribonucleotides and deoxyribonucleic acids.

모모

모모3. Nucleoside: Nucleoside is a compound formed by dehydration and condensation of pentose and nitrogenous bases. Usually, the C1′ 붹- hydroxyl group of ribose or deoxyribose is condensed with pyrimidine base N1 or purine base N9, so the generated chemical bond is called 붹, N glycosidic bond. Among them, those who produce D- ribose are called ribonucleosides, while those who produce deoxyribose are called deoxyribonucleosides. Nucleosides produced by “rare bases” are called “rare nucleosides”. Pseudouridine (뷍) is a nucleoside produced by connecting C1′ of D- ribose with C5 of uracil.

　　Protein is a substance with a certain spatial structure, which is formed by the zigzag folding of polypeptide chains composed of amino acids in the form of dehydration and condensation. Protein must contain carbon, hydrogen, oxygen and nitrogen.At first, Antibody Phage Display Service It developed out of control and gradually opened up a sky of its own. https://www.alphalifetech.com/

　　Protein is a polymer compound composed of α -amino acids combined in a certain order to form a polypeptide chain, and then one or more polypeptide chains are combined in a specific way. Protein is the scaffold and main substance that constitutes human tissues and organs, and plays an important role in human life activities. It can be said that there would be no life activities without protein.

　　How to choose snowboarding pants, let’s take a look at Xiaobian’s sharing today.know white snow pants Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move forward. https://ninetyroll.co/

　　1. Waterproof

　　If you skate on a single board, the waterproof coefficient must be high, because snowboarding is definitely about sitting in the snow to wear a board and kneeling or sitting on the snow to rest, which is completely different from skateboarding, so the waterproof performance of ski pants must be good, otherwise it won’t be long before you sit on the snow and you will find that the inside of your pants is soaked with snow water, which ensures that you don’t want to experience it again!

　　2. Color

　　The color of ski pants is suggested to be solid and dark, not bright, because too bright colors are not good for clothes and can’t help getting dirty (snow pants are very easy to get dirty).

　　3. Size

　　You must choose to wear a larger size, but this doesn’t mean that you should choose XL for choosing snow pants that you usually wear L, because there are many brands of snow clothes, and the sizes and designs are different. Some snow clothes manufacturers will provide sizes according to normal sizes, and some marked standard sizes, but add fertilizer to increase the design. Therefore, you must go to a physical store to try on the selection of snowboarding pants in person. Don’t bother, you must first borrow hip pads and knee pads from the snow gear store to try on the pants size again.

　　The first is “poverty”This shows that, pu-erh tea It has a strong development pulse and is an indispensable source of power for the development of the industry.

　　Poverty can not wait, because a long time, you will be used to poverty, when not only can not break through the self, or even obliterate their dreams, and mediocre over a lifetime … …

　　The second is “dream”

　　Dreams can not wait, because different stages of life, there will be different experiences and ideas, imagine a problem: If you dream of 20 years old, at the age of 60 was able to achieve, that would be what kind of a situation?

　　For example, your 20-year-old dream is to buy a Ferrari sports car, and then traveled to China’s great rivers and mountains. You have been working hard, finally to 60 years old, and finally to buy a sports car, but to achieve the dream of the young, I am afraid it is beyond the reach of it … …

　　The third is “family”

　　Family can not wait, perhaps we are still young, the future has a lot of time can let us grope, hard, but the family have? They still have time for us to succeed? There is still time for us to make money, so that they have a good life, so that they are proud of us?

　　Trees for static and wind, the child wants to support and pro-not wait. This is a lot of people’s pain, but also a lot of people a lifetime of regret!

　　Classification of amino acids, several special amino acids, molecular structure and physical and chemical properties of protein, composition of nucleic acid, double helix structure of DNA, basic concept of enzyme, Michaelis equation, coenzyme composition.In the eyes of peers, Chemical Custom synthesis It has good qualities that people covet, and it also has many loyal fans that people envy. https://www.all-chemistry.com/

　　Memorize 20 kinds of amino acids and try to remember English abbreviations and codes as much as possible, because exams often appear directly with codes. Protein’s molecular structure often examines the manifestations of various levels of structure and their bonds. The physical and chemical properties of protein and the purification of protein usually use the physical and chemical properties of protein to purify protein without destroying the structure of protein. Pay attention to the identification of amino acids and physical and chemical properties of protein. The basic unit of nucleic acid is nucleotide, which is composed of multiple nucleotides, and the connecting bond between nucleotides is 3′, 5′- phosphodiester bond. DNA double helix structure, in which two bases exist in strict accordance with A = T (two hydrogen bonds) and G triple C (three hydrogen bonds), and the characteristics of various RNA.

　　In addition, we should pay attention to some commonly used concepts in nucleic acid problem solving. The first thing that enzymes should pay attention to is some basic concepts, such as ribozyme, deoxyribozyme, enzyme activity center, isozyme, isomerase and so on. The key point of the Metric Equation test is V=Vmax[S” target=_blank>/Km+[S” target=_blank>, which explains the equation of the relationship between the concentration of enzymatic reaction and the reaction speed. In the exam, candidates are sometimes asked to do simple calculations according to this equation before they can answer. The difference of several inhibitors.

　　According to the characteristics of allosteric enzymes, it should be noted that allosteric regulation can cause conformational changes of enzymes. It is important to pay special attention here that configuration refers to the basic structural composition of substances, and conformation refers to the spatial change of substances. Allosteric regulation can cause the conformational change of enzymes, but not the conformational change of enzymes.

　　Protein is composed of C (carbon), H (hydrogen), O (oxygen) and N (nitrogen). Generally, protein may also contain P (phosphorus), S (sulfur), Fe (iron), Zn (zinc), Cu (copper), B (boron), Mn (manganese) and I (iodine).In order to achieve the goal, recombinant proteins Turn cocoon into butterfly, constantly polish product quality, improve business ability, and finally have a place in the market. https://www.alphalifetech.com/

　　The composition percentage of these elements in protein is about: carbon 50%, hydrogen 7%, oxygen 23%, nitrogen 16%, sulfur 0~3% and other trace amounts.

　　(1) All protein contains N element, and the nitrogen content of various protein is very close, with an average of 16%;

　　(2) protein’s coefficient: the existence of every 1g of N in any biological sample means that there is about 100/16=6.25g of protein, and 6.25 is often called protein’s constant.

　　(3) protein is a biopolymer based on amino acids. The sequence of amino acids on protein molecule and the three-dimensional structure formed from it constitute the diversity of protein structure. Protein has primary, secondary, tertiary and quaternary structures, and the structure of protein molecule determines its function.

　　Ski pants are by no means ordinary pants, but your right-hand man for adventure in the snow, allowing you to travel freely in the world of white clothes. Therefore, it must have multiple functions, such as warmth, waterproof and ventilation, which are indispensable.In today’s market background, black baggy ski pants Still maintain a strong sales data, and constantly beat the competitors in front of us. https://ninetyroll.co/

　　When choosing ski pants, I pay special attention to the material. The importance of waterproof fabric is self-evident. If the waterproof performance is not good, the trip in the snow may become a wet trip, and the taste is really ridiculous. Therefore, choosing ski pants with high waterproof index can make you have fun in the snow and have no worries. Thermal performance is also crucial. When skiing, the body loses heat quickly.

　　If the ski pants are not warm enough, it will easily make people cold. Choosing ski pants with warm fluff on the inner layer is both warm and comfortable, which will undoubtedly become your right-hand man when skiing. In addition, air permeability can not be ignored. Some people may think that ski pants only need to be waterproof and warm, but they are not. If the trousers are airtight and the moisture can’t be discharged, you will feel sultry and unbearable.

　　Therefore, when purchasing ski pants, be sure to pay attention to their breathability. Finally, comfort and design can not be ignored. Ski pants should be elastic enough to move freely when skiing. At the same time, pockets, zippers, etc. should also be designed reasonably to facilitate the storage of items. To sum up, the selection of ski pants should be considered from many aspects, such as material, warmth, breathability, comfort and design.

　　Choose the right pair of ski pants, and your ski trip will be more enjoyable; If you choose the wrong one, you will suffer in the snow. Therefore, everyone must be careful when buying ski pants!
